International orders are not eligible for Marine Depot’s free shipping promotions and additional surcharges may apply. It is important to note that not all products we carry can be shipped internationally. Any brokerage fees, tariffs and/or taxes will be billed to you directly by the shipping courier. International customers must use the same billing and shipping address.

The picture is what you get. If you have a newer Kent scraper handle, those blades require notches on each side of the tab in order to slide into your scraper. You can make this modification yourself with a dremmel tool, but it is more work. The locking tab is also not sized to exactly fit the Kent scraper, but friction holds it in place regardless of that defect.In summary cheap, but may require additional work to make it fit if you have the Kent scraper handles I do that require a notch.Hide
